Product Introduction
We developed 3M™ Scotch-Weld™ Structural Core Splice Film AF 3028 FR as a low density, thermally expanding core splice adhesive film with flame retardant properties for filling mismatched areas or reinforcing and splicing honeycomb core. With its expansion rate, this core splice film can effectively join honeycomb core of differing cell sizes.
We balance 3M™ Scotch-Weld™ Structural Core Splice Film AF 3028 FR properties to provide excellent performance with easy-to-use shop handling characteristics. Our heat-curing, easy handling film is designed to meet numerous customer specs in aerospace manufacturing and MRO. Its expansion rate allows for successful joining of honeycomb core of differing cell sizes. Please refer to the Tech Data Sheet (PDF, 28 Kb) for specific information.
We formulated 3M™ Scotch-Weld™ Structural Core Splice Film AF 3028 FR to expand during cure for effective void filling and core splicing and will cure nicely through a range of temperatures, from 250°F (121°C) to 350°F (176°C). This variable cure rate combined with the film’s easy handling gives you flexibility to design efficient processes. Even at slow heat up rates as low as .5°F/minute, AF 3028 FR still reaches full expansion. Its low sag properties and low volatile loss during cure can help provide an excellent solution for mismatched areas or reinforcing and splicing honeycomb core applications where a flame retardant compound is required. It provides high performance from -67°F to 350°F (-55°C to 176°C) to ensure a reliable service life.
